The movable plate 21 is connected by a link 25 with a conveyer belt 26, and the conveyer belt 26 reloads electricity by one Machine is driven to realize that the transverse reciprocating of movable plate 21 moves.
The material detection means 14 detects that PLC controls cut the action of cylinder 22 and cut without PLC is fed back to after material in material volume 11 Fall sizing material material tail, and control upper suction disc 23 to adsorb the sizing material after cutting away material tail, while control the motor driven movable plate 21 that reloads Next station is moved to so that the position of the lower suction disc 12 of upper suction disc 23 and the station corresponds to up and down, then controls compression cylinder 13 to push away Dynamic lower suction disc 12 causes two sizing materials on upper and lower suction disc 23,12 to be sticked together (because sizing material surface has viscosity, upper Under the extruding of suction disc 23 and lower suction disc 12, two sizing materials can be sticked together).One joint 2 that reloads coordinates multiple stations to make With, the sizing material end of a upper station and the sizing material head end of next station can be sticked together, to realize automatic switchover material volume, Realize automation.
In automatic material-changing device, the joint that reloads can coordinate multiple material volumes to use, can be with the specific limits one Secondary property changes material volume, and without arrestment, non-interference, saving time, so as to improve production efficiency.
As shown in figure 4, the accumulator 3 includes vertical plate 31, upper storing first 32, lower storing first 33 and counterweight cylinder 34, The upper storing first 32 and lower storing first 33 are slidably mounted on vertical plate 31 by the way that guide rail is corresponding about 35, the upper storing Transmission mechanism is additionally provided between first 32 and lower storing first 33 to realize that both is defeated towards or away from movement, the counterweight cylinder 34 Go out end to be fixed on lower storing first 33, the side of vertical plate 31 is additionally provided with the stopping device 36 that can fix sizing material, the glue Material passes around between upper storing first 32 and lower storing first 33 at interval in the upper and lower, then is delivered to next station (peace through stopping device 36 Full cut-off knife 4).
The transmission mechanism includes two belt wheels and the synchronization that is correspondingly arranged on vertical plate 31 and can rotate up and down Band, the timing belt suit is between both pulleys and one of belt wheel is connected with a driving motor to drive timing belt to turn Dynamic, the upper storing first 32 and lower storing first 33 are respectively and fixedly connected to the both sides of timing belt.The transmission mechanism can also be leading screw It is specific as follows with the drive mechanism of feed screw nut：The transmission mechanism includes rotationally being vertically arranged on vertical plate 31 Leading screw, be respectively and fixedly connected with a feed screw nut on the upper storing first 32 and lower storing first 33, and two feed screw nuts are anti- Button is connected on the leading screw.Wherein transmission mechanism of the invention is not limited to both the above structure, all to be that by Storing first 32 and lower storing first 33 can be towards or away from mobile transmission mechanisms.
The tension sensor 5 is arranged on fitting motor 9 for detecting the inner tensions of sizing material and by detection signal Feed back to PLC, PLC control counterweights cylinder 34 promote lower storing first 33 with adjust it is upper between storing first 32 and lower storing first 33 away from From, while control leads out motor 8, fitting motor 9 and rotating speed with beam drum 7 to realize the inner tensions of control sizing material.
As shown in figure 1, the safety cutter 4 is arranged between accumulator 3 and fitting motor 9, as shown in Figure 5 and Figure 6, The safety cutter 4 includes fixed mount 41, is symmetrically hinged on two swing arms 42 of the both sides of fixed mount 41, is arranged on two swing arms 42 Between rotating roller 43, spring 44, the cut-off knife 45 being arranged on fixed mount 41, the knife plate 46 and zero being used cooperatively with cut-off knife 45 Level sensor 47.
The spring 44 is sleeved in a fixing axle, and described fixing axle one end is connected on fixed mount 41, and the other end passes through Connecting plate 48 and the bearing pin being arranged between two swing arms 42 connect, and are also threaded with the fixing axle for adjusting spring The adjusting nut 49 of 44 elastic force.The length after spring 44 is compacted, and then realization pair wherein can be adjusted by adjusting nut 49 The adjustment of the elastic force of spring 44, it can thus adjust the setting tension value of sizing material.
Described one end of knife plate 46 is fixed in a swing arm 42, and the other end has been bent to form for coordinating with null pick-up 47 The detection baffle plate used, the breach that can be inserted for cut-off knife 45 is also formed with the knife plate 46.
Gap of the sizing material between cut-off knife 45 and knife plate 46 is bonded after passing through and is squeezed in rotating roller 43, then through fitting Motor 9 be delivered to fitting first 6, when sizing material reach setting tension value when, swing arm 42 overcomes the elastic force of spring 44 to swing, sizing material to The direction of cut-off knife 45 is mobile and sizing material is moved with knife plate 46 by severing, detection baffle plate and deviates zero-bit biography under the cooperation of knife plate 46 The detection range of sensor 47, signal is fed back to PLC to control whole device to stop fitting by null pick-up 47, while retaining fills Put 36 and fix sizing material thereon.Safety cutter there is a possibility that to protect the excessive pulling force of material to make device damage, reach peace Reliably it is bonded entirely.
As shown in Figure 7 and Figure 8, the fitting first 6 includes cut-off knife mechanism, and the cut-off knife mechanism includes mounting bracket 61, fitting Head cut-off knife cylinder 62, double-row angular contact bal bearing 63, connecting shaft 64 and butterfly spring 65, the double-row angular contact bal bearing 63 Including inner ring, outer ring and roller, described one end of connecting shaft 64 and the inner ring are affixed, the other end through mounting bracket 61 side plate to Overhang and the end end is also formed with flange, the butterfly is provided between the side plate of the flange of connecting shaft 64 and mounting bracket 61 Spring 65, the cylinder body of the fitting head cut-off knife cylinder 62 are fixed on mounting bracket 61, the output end of the fitting head cut-off knife cylinder 62 It is hinged with the outer ring, the outer ring bottom is also associated with being bonded head cut-off knife, and the fitting head cut-off knife cylinder 62 drives outer ring to turn Move and drive fitting head cut-off knife to rotate to realize cutting for sizing material.
The first 6 conventional cut-off knife mechanism of fitting, it is bonded head cut-off knife and loosens, there is gap, cuts out disconnected not thorough, the patch after improvement of material The cut-off knife mechanism of syncephalon 6 uses butterfly spring, by controlling elasticity, has the tightening force of an axial direction all the time to connecting shaft 64, keeps away Exempt to be bonded the loosening of head cut-off knife；And the rotation of cutting knife head uses double-row angular contact bal bearing 63, gap is small, can be by tangential force, can Reach good and cut effect.
As shown in figure 1, fitting first 6, which is relatively fixed, is arranged on the top of band beam drum 7, and with beam drum 7 under the drive of cabinet energy Enough rotations are outer can also to realize its axial movement, to coordinate fitting first 6 to complete fitting.Such structure design causes fitting first 6 It is simple in construction easy to control, control time is shortened, the electric feedback loss time is saved, so as to improve production efficiency.
In summary, present disclosure is not limited in the above embodiments, and those skilled in the art can be It is proposed other embodiments within the technological guidance's thought of the present invention, but these embodiments be included in the scope of the present invention it It is interior.
